Includes natural processes within the climate system: orbital patterns, solar radiation, oceans, atmosphere, water cycle, the natural greenhouse effect, carbon cycle, regional climates and differences between climate and weather.

The ocean is the largest solar energy collector on Earth. More than 90 percent of the warming that has happened on Earth over the past 50 years has occurred in the ocean. Not all of that heating is detectable at the surface because currents move some of the heat to deeper layers of water, where it can "hide" for years or decades.

NOAA's Susan Solomon was awarded the 2009 Volvo Environment Prize for her pioneering contributions in atmospheric chemistry and physics.

Forecasters are still calling for a 65% chance of El Nino conditions being met in the next few months. Isn't this late for the start of an ENSO event? 

State of the Climate in 2013

On July 17, NOAA and the American Meteorological Society released the State of the Climate in 2013 report. A 24-year tradition encompassing the work of 425 authors from 57 countries, the report uses dozens of climate indicators to track patterns, changes, & trends of the global climate system.

This is the first of nine lessons in the "Visualizing and Understanding the Science of Climate Change" website. This lesson is an introduction to Earth's climate and covers key principles regarding Earth's unique climate, atmosphere, and regional and temporal climate differences.

This video is simple in its appearance, but it contains a wealth of relevant information about global climate models.

UN Climate Change Learning Partnership Releases Learning Resources Guides on Climate Change Science

The UN Climate Change Learning Partnership released two resource guides to help people understand the science of climate change. The two guides provide a tour of the best & most relevant resources on climate change science.

Sea surface temperatures are up. So why haven't forecasters declared El Niño conditions?
